Dropbox is one of my favorite ways to synchronize and backup files, however, the limit on basic account is only 2GB which is pretty less considering that you can easily fill it up with few vacation pictures and videos. You could use the multiple Dropbox account trick to backup more files though.

Dropbox also provides users with an option to invite friends and get 250MB extra storage for every friend of yours who signs up. But did you know that you can also get 250MB of storage space for free by just clicking on the "Get Started" link in your Dropbox account?
If not, go ahead and login to Dropbox and click on the Get Started link to increase your Dropbox storage space by 250 MB, if you don’t have a Dropbox account yet, you can always use my sign up link to add to my quota
